Title: Improvements in or relating to carpet sweepers
IPC: A47L11/33
Filed: 1943-03-01
Abstract: 562,819. Carpet sweepers. BISSELL CARPET SWEEPER CO. March 1, 1943, No. 3323. Convention date, March 2, 1942. .[Class 138 (i)] The dustpans 6 of a carpet sweeper having a brush rotatable on a horizontal axis are pivoted about axes 7 and springs 9 which press outwards are connected to the pans by means of pivots 11 which are so placed that when the pans are in the closed position the springs 9 tend to keep the pans closed, but when the springs are raised by means of a lever 12, the springs act upon the other sides of the pivots 7 so that the springs tend to hold the pans in open or dumping position as shown. The open position is a slanting one as the motion of the pans is limited by contact of the springs with pins 18. When the sweeper is placed on the floor with the pans in open position, the weight of the sweeper will move the pans to closed position. Specification 529,546 is referred to.

Filed: 1934-07-26
Abstract: 436,425. Slicing - machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., Aden Road, Ponders End, Middlesex.-(Maatschappij van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) July 26, 1934, Nos. 3456/35 (divided out of 436,759), and 30587/34. [Class 28 (ii)] The conveyer of a stacking-mechanism for a slicing-machine consists of a rigid body provided with a plurality of curved prong-carrying parts, and deep grooves spaced by the said parts. As shown in Figs. 3, 4, the conveyer comprises thin curved prong-carrying members 16 and curved spacers 15 secured together by bolts 32. A number of the spacers 15 are formed with radial arms 33 for the attachment of the conveyer to its rotary shaft. In other constructions, Figs. 5, 6, the grooves are formed by flanging the members 151, or by arranging prong-carriers 16<2> in saw cuts in the member 152. The prongs 18, as shown in Fig. 4, are arranged in three groups 18<a>, 18<b>, 18<c>. The prongs 18<a>, 18<b> are substantially radial, but the prongs 18<c> are substantially parallel with the prongs 18b. The discharge fly is so arranged that the slice-engaging faces of its fingers are deflected at 21<1> away from the arc of curvature of the conveyer, so that, as the conveyer moves the impaled slice to the discharge position, the fingers of the fly first remove the slice from the leading radial prongs 18a. The subsequent swing of the fly strips the slice from the parallel prongs 18b, 18<c> without damage to the slice.

IPC: D05B3/08
Filed: 1964-01-27
Abstract: 1,002,098. Sewing machines. MITE CORPORATION. Jan. 27, 1964, No. 3456/64. Heading D1G. A sewing machine buttonhole attachment comprises a base plate, a pivoted actuating arm, a longitudinally-slotted feed bar mounted for longitudinal sliding and lateral swinging movements, a vertical rotary shaft passing through said slot to provide a pivot for said swinging movements, connections between the actuating arm and the shaft for rotating the latter, a cam on the shaft for imparting said longitudinal movements, and means for effecting said swinging movements for encircling a buttonhole with stitching. A base plate 10 is formed with vertical flanges 24, 25 between which is fixed a member 12 for attachment to the presser bar, and which journal a shaft 26. An arm 36, journalled on shaft 26 and engagable with the needle bar, carries a pawl 38 which co-operates with a ratchet wheel 37 rigid with a cam 27 fixed to shaft 26, for rotating the latter. A shaft 20, journalled in base plate 10, is coupled for clockwise movement to a disc 55, journalled on shaft 20, by a uni-directional clutch 53. A similar clutch 54 prevents counter-clockwise movement of shaft 20. A link 50, pivoted at 51 to arm 36, passes slidably through a lug 59 on disc 55, and carries on its screw-threaded free end a nut 61 which co-operates with lug 59 for turning disc 55 and shaft 20 clockwise. A pin 50a on link 50 co-operates with lug 59 for turning disc 55 counter-clockwise. The degree of oscillation of disc 55 is determined by the longitudinal position of nut 61. A pointer 65, rigid with link 50, cooperates with annular grooves 66 on nut 61 to indicate said position. A bar 14 has pivoted thereto at 18 a feeding foot 16, and is formed with a longitudinal slot 15 pivotally engaged with a cam 40 on shaft 20. A cam 39, which is formed with a slot slidably engaging a flattened portion 41 of shaft 20, rests on a flanged portion 21 of shaft 20, and is engaged between abutments 42, 43 on bar 14. Cam 39 carries a leaf spring 47 formed with spaced holes selectively engagable with a pin 49a on flange 21. An arm 34, pivoted on shaft 20, carries a follower pin 30 co-operating with cam 27, and a disc portion 31 engaged in slot 15. Oscillation of arm 36 thereby serves to rotate shaft 26 intermittently for oscillating bar 14 to effect zig-zag stitching around a buttonhole, and also serves to rotate shaft 20 intermittently, whereby cam 39 moves bar 14 longitudinally, the length of the buttonhole being determined by the adjustment of spring 47 and the stitch length by the adjustment of nut 61, while cam 40 swings bar 14 at the ends of the buttonhole for positioning the stitching at opposite sides thereof.

Patent GB-419439-A (GB)
Title: Improvements in and relating to methods of manufacturing electric cut-outs
Filed: 1933-02-10
Abstract: Copper oxide cut-outs are made by heating copper at a temperature just below its melting point, preferably about 1000 DEG  C., to form a layer of red copper oxide, and the conditions of cooling are then controlled to give the required breakdown value. The heated metal may be cooled gradually to room temperature, in which case the breakdown value varies inversely with the rate of cooling.  Alternatively the heat treatment to form the layer of oxide may be followed by an anneal at a lower temperature e.g. from 150-600 DEG  C., the metal being then either cooled slowly to room temperature or quenched. Examples are given in which copper is first heated at 1010 DEG  C. and then annealed at a lower temperature, in one case at 150 DEG  C. followed by slow cooling and in another at 480 DEG  C. followed by quenching, the latter giving a lower breakdown value.
